Take a look at either the SendMessage() or PostMessage() API calls in MSDN.

If you have a handle to the child window, just use SendMessage(). Otherwise, if you are using MFC, does SendMessageToDescendants() help?

So what exactly is your question - how to send a message to a child window, or how to use Spy++?

Have you looked into ShellExecute(..., "open", ...)?

I have much older program, they using old way about pointer.
// Old code 1
void Func()
{
char *p = "Hello";
*p = 'h'; // It has "Access Violation" probelm in VC++6.0!
}
// Old code 2
void Func()
{
long ptr;
char p[];
ptr = p // has problem with type !!
}
Shoud I change all bad code ???? Do we has nother way to use older codes?

char p[];
There must be a number of some sort holding the brackets apart (e.g., char p[5]), or p must be initialized to something that has a size (e.g., char p[] = "Hi").

Yes, most definitely!

I means let the old program running well on VC++ 6.0. Because the old program made on VC4.0, and it work well. The program is very big, so i would not like change it.
Thanks

*p = 'h' tries to modify the memory holding a string literal. This is not something you should do because the memory might be read-only (thus generating a GPF when you write to it). Even if it works, it may not work on all compilers or OSes.

What if your memory is properly allocated? See my other post in this thread for an example.

That's a huge no-no for a number of reasons, and a memory error waiting to happen. For one, if you don't allocate your memory, you're not guaranteed to have it available for your program to use.
Instead Func() should look like this:
void Func()
{
char p[] = "Hello";
*p = 'h';
}In this instance, *p acts just like p[0].

Use GetTempFileName().

Hello!
I have an edit box on a pop-up window that receives messages from the main program and displays them. Right now I am using the SetDlgItemText to set the edit box text, and then using RedrawWindow to send the text.
My problem is this: using the commands listed above, the previous string is deleted when the new text is sent. For example, if I first send a string to the text box, that text is deleted when I send another string.
I am wanting to add another string on the line below the first string, without deleting it. For example, I want to send the first string to the text box and display, then I want to send the second string and display it under the first string. I do no know how to make the text not disappear every time I send a new string.
Thanks for your help,
Loren

How do you send the test to the edit box? Are you sending an actual windows message or an arbitrary message and the updating the edit box?

It sounds like you need to use CEdit::ReplaceSel() instead, or use a listbox instead of an edit control.

Get the current text from the edit box (GetDlgItemText) to a buffer, append a newline to the end of the buffer, append your new message to the end of that and then send the whole lot back to the edit box (SetDlgItemText). Of course, you could just keep your buffer between messages and then you wouldn't need to get the current text each time.
If you want a better solution then use EM_SETHANDLE to set the handle of the buffer the control is displaying and then manage the buffer yourself.
Hope that helps, good luck.
